Hi All
I've had my tank up and running for about four months (journal here).
My Siamensis 53B has for the last month or so been exhibiting what I think is a nitrogen deficiency. Yellowing and melting older leaves, small new leaves, bit of a red-ish tinge to the new growth. Others have noted the same in my journal. This is becoming something of a problem now, so I think 'ignore' is not on my list of options.
Weird thing is that a) my Nitrate test kit is showing a very red result and b) my limnophila sessiflora is super-happy. My frogbit...not sure.
Pics attached. Really appreciate any advice or pointers.
Things I have thought of:
1. start dosing TNC Lite (currently dosing TNC Complete) to up the micros without overdoing it on the NPK especially with the N already relatively high in the water column.
2. trim and replant some of the 53B to see if that prompts a change
3. turn off the airstone
4. stop gravel-vac-ing the substrate (I don't do an especially deep 'vac', and anyway avoid the planted areas)
Things I have done:
1. added some more root tabs under the 53B.
Other relevant info: nitrates out of the tap - 20-30ppm, tank pH around 8.2, inhabitants: one small but growing plec and four corys. HoB with coarse filter, fine filter, and 'biohome'-type media. gravel substrate, a few Kg's of glimmer wood substrate. Changing water around 50% once a week. Temp around 22C (although currently around 24).
Many thanks for any help!
